Where: Jiangsu, China (32.1° N, 119.1° E: paleocoordinates 4.2° S, 125.2° E)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Fentou Formation, Wenlock (433.4 - 427.4 Ma)
• Except where otherwise stated, ref. 7624 uses Lower Silurian as equivalent to Llandovery, Middle Silurian as equivalent to Wenlock, and Upper Silurian as equivalent to Ludlow plus Pridoli. "The age of the Fentou is still debated. There are two opinions, one... Late Llandovery-Early Wenlock..., and the other considering that the presence of Sinacanthus and Kiangsuaspis indicates a Late Silurian, or possibly even a Devonian age. However, we feel that this last opinion is of dubious validity, particularly in view of the uncertainty concerning the taxonomic status of both S. and K. [After consideration of other vertebrate material from various localities], little doubt now remains about the early Middle Silurian age of this long-discussed material that includes some vertebrates." [Vertebrates are in lower and middle beds. Correlation chart shows formation as a whole spanning much of the Wenlock.]
